Concept explainers
Interpretation:The distance of the pump from the liquid level in the reboiler should be determined which give a net positive suction head of 2.5 m.
Concept introduction:NPSH refers to the Net Positive Suction Head. It is the excess pressure or head to the vapor pressure which is applied to the pump at the inlet in order to avoid the cavitation. Cavitation is a situation which reduces the capacity of a pump and causes severe problems. NPSH is given as,
